Genebre 2450 – Flanged Check Disk Valve PN16
The Genebre 2450 is a flanged, disk-type check valve designed to prevent reverse flow in water networks and compatible non-hazardous liquids. Operation is automatic, actuated by differential pressure and flow direction, with no external actuator required. The technical datasheet refers to this model as a flanges ends check disk valve.
Technical Specifications
- Size Range: DN50–DN250 / 2"–10"
- Pressure Class: PN16
- End Connections: Flanged, DIN 2501 PN16
- Max Working Pressure: 16 bar
- Operating Temperature: -10°C to +100°C
- Seat Material: NBR
- Not suitable for steam service
Construction Materials
Body and disk: cast iron EN-GJL-250 / GG-25 with epoxy coating. Guide and shaft: nickel-plated brass (up to DN100), nickel-plated GG-25 (DN125–DN250). Spring: stainless steel. Sealing: NBR.
Hydraulic Data
Kv values range from 95 m³/h (DN50) to 1750 m³/h (DN250). Minimum opening pressure depends on installation orientation and size, typically 17–68 mbar in standard layouts.
Applications
Applicable for pump stations, heating/cooling circuits, industrial water, water circulation, and auxiliary hydraulic systems. Selection should consider flow rate, Kv, allowable pressure drop, NBR compatibility, and temperature limits.
Installation & Maintenance
Piping must be free of debris, weld residues, and foreign objects. Do not install immediately downstream of pumps, elbows, reducers, or other valves; maintain 10×DN upstream and 3×DN downstream clearances. No lubrication required. Inspect for leakage and check for loose or corroded connections.
FAQ
Can it be used with steam? No.
Does it have an actuator? No, it operates via flow and differential pressure.
When is it not suitable? For temperatures above +100°C, steam, or fluids incompatible with cast iron and NBR.
Description
Certificates
GENEBRE, S.A. has implemented a quality management system to control the designing and manufacturing of fluid control valves, as well as the distribution of home and public taps.
This system complies with the requirements of the current international UNE-EN-ISO 9001:2015, certified by the prestigious German certification organization TÜV Rheinland.
In 2000, GENEBRE began to comply with the European Business Excellence Model, more commonly known as the EFQM. As a result, in 2003, the Catalan Regional Government awarded us with the Quality Award. This new system enables us to ensure the quality of GENEBRE's products and also to offer added value to our clients.
In 2012, we obtained the certification for the Environmental Management System. This system is certified according to the UNE-EN-ISO 14001:2015, also by TÜV Rheinland. GENEBRE QUALITY AND ENVIRONMENTAL POLICY
